Unauthorised modifications of navigation lights

COLREG requirements and limitations Due to attempts to comply with the Singapore Strait recommendations to show three green all-round lights when crossing the Singapore Strait, therre have been lately unauthorised modifications of navigation lights. DNG GL has issued Technical Newsletter to to inform/refresh ship owners, managers and their crew about the COLREG requirements and limitations and also about the regulations applicable to vessels navigating the Malacca and Singapore Straits According to information received from the Australian Maritime Safety Authority (AMSA), an alarming number of vessels passing Singapore have been observed to have illegal modifications of their COLREG navigation RAM/NUC lights.Vessels have been observed with the RAM/NUC navigational lights' globe or screen painted the wrong colour in order to comply with the Singapore Strait Traffic Separation Scheme (TSS). However, by doing so, the vessels are no longer in compliance with the COLREG RAM/NUC requirements.These violations may have undesirable consequences. After these changes, the vessels can no longer display the correct COLREG lights, thus posing a serious threat to navigational safety due to the increased risk of collision. In addition, port authorities, such as AMSA, will detain vessels observed to have such illegal modifications. In December 2010, IMO published new amendments to ...

New Alaska navigational chart makes increased Arctic shipping safer

Kotzebue Harbor chart replaces measurements last taken in 19th century NOAA formally presented today to Alaska officials a new nautical chart for Kotzebue Sound in the Alaskan Arctic, a sparsely charted region that is seeing increased vessel traffic because of the significant loss of summer sea ice.The new chart depicts the full range of depth measurements and object detection acquired during a full ocean bottom survey last summer by the NOAA hydrographic survey ship Fairweather. It replaces a chart showing depth measurements last taken in the 19th century spaced three to five miles apart, leaving room for possible undetected dangers in between.The new navigational chart addresses a pressing need for this Northwest Alaska transportation hub, located in the Arctic Circle. Barge shipments and large transport ships must be anchored at least 14 miles out in the Kotzebue Sound due to shallow waters and inadequate charts and navigational aids. Freight must then be transferred by smaller barges to Kotzebue."This new chart is just one of the many critical navigational services that NOAA provides to support safe navigation and maritime commerce while protecting important marine resources," said Kathryn D. Sullivan, Ph.D., deputy NOAA administrator and assistant secretary of commerce for environmental observation ...

SAM Electronics Launches New Series of Bridge Navigational Watch Alarm Systems

Designed for simple installation aboard Hamburg-based SAM Electronics, an L-3 company, has launched a new series of Bridge Navigational Watch Alarm Systems (BNWAS) designed for simple installation aboard both new and existing vessels of any type or size in accordance with IMO carriage regulations due to become effective from this July onwards.Type-approved by major international classification societies such as ABS, GL, Class NK and RINA, the advanced alarm and monitoring series ensures enhanced safe vessel operation via continuous surveillance of bridge activities, including detecting any operator malfunctions that could lead to accidents. Alerts can be automatically relayed to the ship's captain and other watch personnel with the alarm system and all backup call functions and timer settings controlled and handled from the bridge console's centralised alarm panel.Basic features of the SAM BNWAS include main alarm panel with dimming, ship accommodation alarm panels, an assist call facility, motion sensors, reset push buttons, activation switch, reset timer inputs from radar, and force activation via steering gear and/or Trackpilot supported by flexible interfaces.Systems also meet latest IEC 62616 performance standards and are optionally available either as stand-alone units or for integration as part of the NACOS Platinum range of all-purpose integrated bridge management ...
