Introduction

Traditionally ship’s bridges have been characterised by strong hierarchical organisations. The Captain’s arrival on the bridge would almost always mean their taking over the conning of the ship. That would also mean that all important decisions on heading and speed were based upon a plan which resided solely within the Captain’s head. This environment had the effect of making the other Bridge Officers passive bystanders, and turning a team effort into a solo operation. Over the last three decades we have experienced a number of high profile accidents where one of the main contributing factors stems from this type of working environment.

In the early 1990’s the industry saw the introduction of Bridge Resource Management (BRM) as a solution to stop accidents caused by single point failures, but unfortunately, this has not been entirely effective. The BRM courses focused a lot of attention on developing assertiveness, encouraging Officers to speak up when a senior Officer deviated from the plan. It is easy to discuss assertiveness in a classroom, and train it in a simulator environment, but it is very hard to implement in real life - unless the Captain is proactively implementing a working environment where speaking up is not only accepted but encouraged.

Even with a culture of challenge well established in an operational environment, there is another problem. If a junior Officer does not know what the operational limits of a route or berthing plan are, it’s difficult to challenge their execution. The trigger for a challenge should be based upon a perception that the person with the Conn has deviated either from the plan, or from the agreed limits of that plan. Therefore, there must be an agreed and mutually understood Voyage Plan from berth to berth where navigational and speed limits are displayed and highlighted during briefings.

All sectors of the maritime industry face challenges. These challenges tend to be unique for the companies and vessels involved. In Carnival Corporation we have realised that the BRM course alone is not sufficient for us to improve safety to the required level. Given the demands of operating a large cruise ship in confined waters, we can no longer be dependent upon the talent of a single individual no matter how skilled that individual may be. Finally, there is also a need to effectively and seamlessly integrate visual and instrumental navigation techniques by actively monitoring bridge equipment and sensors. All of these challenges require that everyone on the bridge must work as a co-ordinated team.

However, for very good reasons it remains vital that only one person is physically giving the orders and executing the plan – so that one person must be both effectively supported, and effectively challenged, by the rest of the team. The means we have identified to provide this support and increase the probability of challenge was to move the Captain from active conning to a monitoring and leadership role.

This transition into an organisationally based safety management system was novel for the cruise industry, and has generally been perceived as a positive move in the industry’s evolution to counteract incidents emerging from a single person error. That said, it became apparent that this approach needed to include more than just our own staff. We also needed to include the Maritime Pilot - who previously had not been directly involved in our training process. Considering the vital importance of this member’s role when entering and leaving harbour, this was something we felt we needed to correct. This is why we are now inviting Maritime Pilots to actively participate in the professional development of cruise ship personnel, and as a result, work more closely with the bridge team during their time on board.

It is fully understood that Pilots have limited time between arriving on our ships and assuming their role, during which time they assimilate a great deal of information. It is hoped that by applying this system across all of our ships, the process of preparing and briefing will be made simpler and faster for all concerned. We are also fully aware that we are not alone in wishing to improve navigational safety, and that several Pilot organisations have led the way in introducing new technological solutions, such as dynamic under keel clearance measurement systems, extremely accurate navigation sensors, and route plans with waypoints available on the web. Indeed, safety is the number one priority for all of us in the industry.

The purpose of this paper is to explain how the Bridge Resource Management (BRM) system came into existence on Carnival Corporation ships, how it currently works and how we would like to include Maritime Pilots in that system.

New Bridge Organisation

In 2008 two of Carnival Corporation’s operating lines P&O Cruises and Princess Cruises introduced the new bridge organisation based on roles rather than ranks. Under this approach, the officers would operate as a coordinated team managing the bridge, with each assigned a role associated with specific functions and tasks. The purpose was to create a more efficient, engaged and resilient organisation where high workloads could be managed and balanced in response to external and internal circumstances, and decisions were analysed by default rather than exception.

The system builds on an airline industry concept by introducing Navigator and Co-Navigator roles. The Navigator, who is conning the ship, is required to communicate intentions to the Co-Navigator, who should have prior experience in the Navigator role. The Co-Navigator’s tasks include monitoring, cross-checking and supporting the Navigator. When the demands of the situation increase, also the manning will increase, as they are further supported by an Operations Director, who must be a senior person, normally the Captain or Staff Captain. The role of the Operations Director is to maintain an overview of the operation and provide guidance as required. There is also an Administrator to manage alarms and internal communications. A Helmsman and a lookout complete the team.

The Navigator role is usually the most junior qualified Officer of the team and the Operations Director the most senior, but this can be changed as circumstances require. Each Officer regardless of rank has a stated responsibility to speak up if the vessel is about to come outside agreed limits in the voyage plan or should they have any other concern. This represents a significant change in bridge management, and it has proven to be extremely effective in improving the overall operation and, most importantly, reinforcing safety as the highest priority.

This role-based bridge organization does not in any way diminish the authority and responsibility of the Captain, who as Operations Director maintains full oversight of the bridge and assigns Officers to particular roles based on their competence and experience with the upcoming operation. The role of the Operations Director is to monitor the operation and supervise and provide guidance as appropriate whilst always retaining the option to step in and take the Conn if required. As the Navigator is often comparatively junior, this early, mentored responsibility has already produced a general increase in ship-handling confidence amongst our young Officers. Also, as it is the Navigator who is stating intended course of actions and executing them, and since both the Co-Navigator and Operations Director are senior in rank, those actions are far more likely to be challenged than if the responsibilities were reversed. It is probably worth emphasising that this process of challenge has not turned the Bridge into a Democracy, nor does it represent distrust – responsibilities and authority remain the same, and challenges are there to ensure that any intended deviations from the agreed plan are detected, and the reasons for them understood.

Communications

In addition to the Organisational changes, we have introduced new ways of communicating intentions and orders to both reduce confusion and to encourage challenges. The first of these is described as “Thinking Aloud.” It is used by the person with the conn to set out the plan, reasons and expected outcome. For example:

  • Plan: “I plan to start the turn one cable early...”
  • Reason: “As we have a following current ...”
  • Outcome: “So that we should end up on track as the turn completes.”

The Co-Navigator then checks if this is safe and if so, agrees to the suggested change of plan. This method not only encourages challenges, but also helps build a shared mental picture between team members.

The second change to how we communicate is the use of the “Closed Loop” method. This is used to ensure that orders and vital information are correctly received and understood. The communication is between two persons, following is an example of an order using this method:

  • Pilot/Navigator: “Helmsman, come starboard to 030°, rate of turn 10°/min.”
  • Helmsman: “Starboard to 030°, rate of turn 10°/min.”
  • Pilot/Navigator: “Yes.”

After completing the turn the helmsman may communicate the following:

  • Helmsman: “On Course 030°.”
  • Pilot/Navigator: “Thank you.”

The ‘Closed loop’ system may be familiar to some, as it resembles the practice traditionally used by traffic controllers in the aviation industry and some naval vessels. The repetition by the person receiving the order (the “Receiver”) informs the person giving that order (the “Transmitter”) that it has been correctly heard. The confirmation from the Transmitter reassures the Receiver that they have understood the order. It is worth noting that this is a confirmation process, NOT a questioning one.

Implementation

This fundamental change in professional culture had to be introduced in several stages, starting with the development of new bridge procedures for normal as well as abnormal and emergency operations. Officers needed to know why this change was needed and how it worked, so an extensive training curriculum has been developed that covers the roles-based approach. This training includes insight on human performance, and its limitations, to explain the rationale behind the new procedures and bridge organisation. The process of implementing these changes across our fleet has now been completed, and we think that the result of this transformation has moved our whole approach to operations towards a higher level of safety, with our Officers making effective use of both the new structure and our constantly evolving bridge technology.

In order to consolidate this change ten Captains have been taken out of rotations and trained to become instructors and employed as Fleet Captains going around the fleet to first help Captains with the implementation and now making sure that operations are carried out as intended.

Furthermore, an annual Proficiency, Training and Assessment (PTA) programme has been introduced for all officers who have completed the all required training. The PTA includes two days of evidence based training and two and a half days of proficiency assessment, where a minimum standard must be achieved, if not, further training will be required.

The Maritime Pilot as Part of the Team

So, with the internal processes in place, it now makes sense to look at how best to incorporate Marine Pilots into the system. If the assumptions that were made to require change to our bridge organisation remain true – that modern bridge operations are too complex for even an experienced Captain who is intimately familiar with his ship to handle alone - it makes sense that we cannot reasonably expect Pilots to single-handedly execute those operations even given their extensive knowledge of the local environment. So just as our internal approach has evolved, it is equally important to look at how the Pilot’s role fits with this team-based approach.

Some Pilot organisations claim that their members cannot be fully integrated members of the bridge team. This concern is fully understood, as altering the Pilot’s traditional role can be seen by some as an increase in risk regardless of the competence of the team they are joining – particularly when that Pilot is no longer expected to actively conn the ship but to supervise the team. This is why there are alternatives from which a Pilot can choose to determine how they interact with the team. Regardless of the method chosen, however, we encourage the use of the new Communication procedures as previously described, to ensure that other team members (and the Helmsman in particular) are not confused by instructions given in an unfamiliar format. This is particularly important if a Pilot takes the Conn.

Option 1. This is when the Pilot takes direct control of navigation, which includes the following:

  • At the tactical level the Pilot takes the Conn, giving orders regarding engine settings, heading, rate of turn, etc.
  • At the strategic level the Pilot makes strategic decisions regarding going outside the track corridor and use available safety margins under abnormal situations.

Option 2. This is if the Pilot takes indirect control of navigation:

  • At the tactical level the Pilot delegates the conning decisions and actions to the Navigator who will operate the ship according to the mutually agreed voyage plan. The Pilot supervises, and provides guidance and direction when required.
  • At the strategic level the Pilot makes high level decisions to deviate outside the planned operational limits and to use available safety margins in abnormal situations.

It is probably obvious that Captains on cruise vessels with a well-trained team would prefer Option 2, as that enables the bridge team to remain actively engaged with the Pilot providing an additional layer of safety. This option leaves the two most senior people on the bridge, Captain and Pilot, monitoring.

the progress of the vessel. They would not hesitate to speak up if there would be a reason for that, which has been the case when the Captain or the Pilot has had the conn. However, it is fully understood that in some areas this is not possible due to legal restrictions. It should be noted that Piloting with Indirect control of navigation is not a CSMART invention, it has been around for a long time in certain parts of the world.

Voyage Plan

The Transport Safety Board of Canada wrote in their Marine Investigation Report M12W0207:

The absence of a detailed, mutually agreed-upon passage plan (“shared mental model”) deprives bridge team members of the means to effectively monitor a vessel’s progress, compromising the principles of BRM.

We fully agree with the above statement that one of the key factors in effective teamwork is making sure that the plan, and its operating parameters, are mutually agreed and understood by all concerned. Given that some of our port operations can involve narrow margins of error and long, complex routes and tight manoeuvring space, it is unrealistic to think that a detailed information exchange and planning can be performed and agreed upon at the pilot boarding place. It would be ideal if there were a means of mutually agreeing the plan prior to Pilot embarkation as this would result in the Master-Pilot exchange being based upon an already mutually understood plan, where any deviations from that plan due to the real-time circumstances are discussed. This is already in effect in some ports, and we would very much like to discuss the possibility of broadening this concept to all the areas in which we operate.

There is tremendous potential for mutual development and understanding by collaboratively working in high fidelity ship simulators. To complement our courses we also have a programme called ‘Port & Ship Familiarisation.’ This programme consists of workshops and simulator exercises where Bridge teams and Pilots work together focussed on a particular ship (or class of ship) using a given port. Using expertise from the Pilots and Captains, and employing classroom workshops for planning followed by simulator execution, the end result of this is a mutually agreed navigational plan, including operational parameters and tug considerations. Feedback indicates that this type of collaborative effort enhances safety and efficiency as well as working relationship.

Conclusion

Navigating a large cruise ship in confined or restricted waters involves risks that must be managed carefully, so that safe operation is maintained by using all available resources effectively. This is exactly what Carnival’s new role based bridge organisation is pursuing.

At CSMART we have considerable experience in Port Pilotage and Cruise ship navigation. This experience tells us, quite clearly, that if we want both professions to evolve together towards a more efficient working relationship we should do it with mutual understanding and respect. One step in this direction can be realised if Pilots and bridge teams would join forces in high fidelity simulators and together assess the risks and agree on a plan including safe operating parameters. With an already agreed upon plan, this would provide for a much more effective master pilot exchange, which should include only last minute contingencies that force changes to the agreed plan.

The foundation of all understanding of human life is that no static maintenance of perfection is possible and it matters little how distinguished the past. Advance or decadence are the only choices offered to mankind. The pure conservative is fighting against the essence of things.
