How LR is supporting battery technology in shipping

https://www.youtube.com/watch?v=7uVN2QzH4us An interview with Louise Dunsby, Lead Electrotechnical Specialist, Marine Technical Policy Group, Lloyd’s Register. Louise talks about the changing face of battery technology in shipping, and how LR is adopting a non-prescriptive risk-based approach to ensuring battery safety for our clients’ vessels.

LR’s capability in computational fluid dynamics

https://www.youtube.com/watch?v=gJ3Blyn7H0w An interview with Chris Craddock, Fluid Dynamics Manager, Technical Investigations, Lloyd’s Register. Chris talks about LR’s expertise in computational fluid dynamics (CFD), and in particular how LR performs CFD at full scale and using design optimisation, to help its clients realise more innovative designs.

First vessels to comply with LR's stern-first ice class rule

Three Arc 7 shuttle oil tankers being built at Samsung Heavy Industries shipyard at Geoje in South Korea and contracted to the Russian operator Sovcomfl ot are the first newbuild vessels to comply with LR’s provisional rules for the classification of stern-first ice class ships. The 42,000 dwt ships, which are dual classed to LR and the Russian Register, will be purpose-built for year-round shuttle operations exporting oil from the Novoportovskoye oilfield in northern Russia via Ob Bay in Russia’s polar area. Their ships’ design is notable for its widebeam, shallow draught configuration with twin-podded propulsion units and a bow-loading system for offshore loading in Ob Bay’s shallow waters. Compliance with the requirements of the Russian Northern Sea Route Administration (NSRA) will ensure a specification of sufficient ice strength for the likely environmental conditions the ships will encounter in year-round operations in Ob Bay and the Kara and Barents seas. Compliance with LR’s provisional rules’ requirements will ensure the ships reflect best practice for stern-first operation in ice including, for example, appropriate extents of stern shoulder ice strengthening, best practices for navigation bridge watch layout and visibility and consistent interpretations of international regulations when operating stern-first in ice – as ...

LR approved as independent laboratory by USCG for BWTS approvals

  Lloyd’s Register (LR) has been approved as an independent laboratory (IL) and will begin testing of Ballast Water Treatment Systems (BWTS) to meet the United States Coast Guard (USCG) requirements. The USCG regulations for the approval of BWTS came into effect in 2012. The regulations began to require the installation of improved BWTS onboard seagoing vessels from 2014. All vessels that trade in US waters will be required to have an approved BWTS from the first dry-docking after 2016. LR has signed a Memorandum of Understanding (MoU) with the Ballast Water test facility at DHI Denmark and the electro/technical testing company DELTA. These leading test facilities, supported by LR’s surveyors and statutory experts will conduct testing as part of our collectively recognised IL.  Flans Kemp, LR’s Global Business Development Leader for Type Approval, commented: "For Ballast Water Treatment Systems equipment manufacturers, the challenge is in understanding the differences between the type approval regimes, and ensuring that their equipment has undergone all the necessary testing to obtain approval to meet the relevant regulations. LR can help manufacturers to understand the different regulatory regimes with differing requirements and streamline their testing and approval activities to minimise the time and costs involved ...

Key hazards to Large battery installations

  Lloyd's Register (LR) issued a new guidance document aimed at facilitating a risk-based approach to battery use. The guidance describes the key hazards to consider when installing battery technology, and gives an overview of our non-prescriptive approach to approval. The guidance also covers battery chemistry and industry standards. Using batteries to supply ships’ power systems can improve efficiency, save fuel and reduce emissions. Battery installations also give a significant reduction in noise and vibration compared to traditional power systems. There are currently no international standards for large marine battery installations. However, the International Electrotechnical Commission (IEC) is developing two standards: 62619 and 62620. There are also requirements for transportation of batteries such as the UN 38.3 Recommendations on the Transport of Dangerous Goods – Manual of Tests and Criteria. Several vessels have already been classed under LR’s novel design Rules and the interest in large battery installations from shipbuilders and battery manufacturers is continuing to increase. It is important to note that the range of available cell chemistries makes it unfeasible to have a prescriptive set of rules for batteries. LR recognises that lithium-ion is the most commonly-used type of cell at present, but even within the lithium-ion family ...

LR to class versatile icebreaker for Canadian Coast Guard

  One of the world’s largest and most powerful icebreakers, John G. Diefenbaker, is being built for the Canadian Coast Guard (CCG) in Vancouver as part of the Canadian government’s National Shipbuilding Procurement Strategy (NSPS). The 150m long vessel will be constructed by Seaspan Vancouver Shipyards. Her design, which is a collaboration between the CCG, VARD Marine, Aker Arctic Technology and Imtech, is based on the requirements of Lloyd’s Register’s polar class 2 requirements – the second highest ice class according to the IACS polar class rules. The vessel is also one of the first to hold the class notation ‘Icebreaker(+)’, where ice strengthening requirements are additionally validated with an analysis of the vessel’s operational profile and potential ice-loading scenarios.  The John G. Diefenbaker, which was named after the former Canadian prime minister whose government founded the CCG in 1962, is designed for unrestricted autonomous operation in the Canadian Arctic and adjacent waters for nine months of the year with the capability of safely over-wintering in high Arctic waters. The vessel will be able to break 2.5m of snow-covered ice and will have an icebreaking endurance greater than 25 days. She has an open water range of 26,200 nautical miles ...
