Watch: FPSO hull construction

The ‘Power’ FPSO hull (Floating production storage and offloading) floated out from dock of the COSCO’s shipyards in Zhoushan, China in September, about 10 months after first steel cut. Normally, the hull completion was expected to be complete in 12 months. 

Port of Rotterdam expects Black Marlin, transmitting 18 hulls

Port of Rotterdam awaits for the arrival of the Black Marlin, on Monday, August 12. The vessel has 18 inland hulls onboard and a crane ship for Damen. The 18 hulls were built in China. The construction of the hulls in China was to be sure of a cost efficient product.

Two bulkers collide on Singapore anchorage

Two bulk carriers, ‘Spring Snow’ and ‘Klima’, collided on 4 July within Singapore port waters. The incident took place while the two vessels were performing bunkering operations. The damages to ‘Spring Snow’ are not known, while ‘Klima’ sustained hull breach in the cargo hold area, as well as water ingress. 

Requirements for maintenance of lifeboats and rescue boats to launch

ClassNK presents requirements for maintenance, thorough examination, operational testing, overhaul and repair of lifeboats and rescue boats, launching appliances and release gear. Thus, following (MSC 96) IMO Resolution MSC.402(96) the launching of appliances and release gear was adopted, similar to the adoption of the amendments to SOLAS III/3 and III/20 to make the MSC resolution mandatory.

Draft guidelines of heat transfer analysis of liquefied gas carriers

The Korean Register issued the Guidance of Heat Transfer Analysis for Ships Carrying Liquefied Gases in Bulk/Ships Using Liquefied Gases as Fuels, highlighting that the cargo tank of the vessels transmitting liquefied gases in bulk or the fuel tank of ships using liquefied gases as fuels is likely to make the hull structure cold due to the low temperature of the liquefied gas. 

Non-lethal hard fouling able to prevent barnacles from attaching to the hull

During a 40-month trial of an antifouling coating containing an anti-barnacle active agent, barnacles failed to anchor themselves to the tanker’s hull. The technology activated the barnacle larvae’s octopamine receptor, keeping them in swimming mode and preventing them from attaching to the hull with non-fatal effect.

The path to maximum hull efficiency

During the 2019 GREEN4SEA Conference, Mr. Tom H. Evensen, Sales Director for Jotun’s Hull Performance Solutions and Mr. Manolis Levantis, Analyst Manager, focused on hull performance for ships. Mr. Evensen and Mr. Levantis highlighted the major impact that such a feature has on a vessel’s efficiency. They also noted that in order to achieve the ideal hull efficiency, proper surface preparations are vital.
