Feature 3 | RO-RO FERRY REPORT PROPOSED AMENDMENTS TO SOLAS, PART B-1, REGULATIONS 8 AND 9


Regulation 8 – Special requirements concerning passenger and cargo ships stability 3.6 where long lower holds are provided in passenger ships or cargo ships other than tankers, the Administration may require an increased penetration of 0.2B, but not less than 3m, measured inboard from the ship side, at right angle to the centreline at the level of the deepest subdivision draught.


4 Spaces, that would be flooded, when the assumed extent of damage in paragraph 3 is applied, shall not render emergency power and lighting, internal communication, signals or other emergency devices inoperable in other parts of the ship.


5 Where passenger ships and ro-ro (cargo) ships are fitted with ro-ro decks or long lower cargo holds the particulars of non- contributing damages (s = 0 and p > 0.00), including full details of the calculated factors, should be examined to confirm that these will not initiate a rapid capsize.


6 Where the residual freeboard (fr) is less than 2m between the damaged ro-ro deck and the final waterline at the location of the damage, then the administration may require additional investigations to be carried out to demonstrate compliance with their own requirements or SOLAS/CONF.3 – Resolutions of the Conference of Contracting Governments to the International Convention for the Safety of Life at Sea, 1974 – (November 1995) – Resolution 14 – Regional agreements on specific stability requirements for ro-ro passenger ships – (Adopted on 29 November 1995) – Annex – Stability requirements pertaining to the agreement.


Regulation 9 – Double bottoms in passenger ships and cargo ships other than tankers


9 In case of large lower holds in passenger ships and cargo ships, other than tankers, the Administration may require an increased double bottom height of not more than B/10 or 3m, whichever is less, measured from the keel line. Alternatively, bottom damages may be calculated for these areas, in accordance with paragraph 8, but assuming an increased vertical extent.


Second vehicle carrier in line for Hawaii trade


David Tinsley reports on a new American built, but Croatian designed ro-ro ordered by Pasha Hawaii for Hawaian trade with the USA mainland.


A


second pure car/truck carrier (PCTC) has been ordered for the Hawaii/California trade lane,


giving a fillip to ro-ro vessel construction in the USA. Pasha Hawaii’s contract with Singaporean-owned, US shipyard VT Halter Marine calls for a newbuild based on the 37,500gt Jean Anne, introduced to the Hawaii traffic in 2005. Te proven design originates from the Uljanik yard in Croatia. Pasha Hawaii anticipates delivery of the US$144 million new vessel during the second half of 2013. Its commissioning will enable the operator to implement a weekly sailing frequency, compared with the fortnightly service currently afforded by Jean Anne, the company’s sole ship. Pasha Hawaii is a joint venture between automotive logistics specialist Te Pasha Group, of California, and Hawaii Ship Management, of Connecticut. Engineering teams from Uljanik Shipyard

and VT Halter Marine are collaborating with Pasha to finalise the nascent vessel’s technical specification, aimed at ensuring optimum long-term performance as regards both operating efficiency and environmental standards. Located in Pascagoula, Mississippi, the yard has also signed an option agreement covering a further newbuild, with some scope for variation, for a base price of about US$137 million. Jean Anne is a product of the Pascagoula


yard, having been originally contracted from the shipbuilder when it was Halter Marine, as part of the Friede Goldman Halter group. Te vessel was finally completed aſter Halter Marine’s purchase by VT Systems, a US subsidiary of the Singapore company ST Engineering, and following the negotiation of a new deal with Pasha. Jean Anne was a milestone vessel for the industry, as the first PCTC turned out by a


US shipyard. Now in her sixth year of service, and catering to multifarious types of ro-ro cargo through fortnightly calls at San Diego, Honolulu, Kahului and Hilo, it is the only ship of its type in the Hawaiian trade. As the template for the newbuild project,


Jean Anne embodies 10 cargo decks, three of which are hoistable and three of which are heavily strengthened, giving a total garage area of 387,000ſt2


. Access is by way of a 100tonnes


stern quarter ramp and 20tonne shell ramp, both on the starboard side. The single, 11,050kW two-stroke MAN main engine provides for a service speed of 20knots. “Building a second ship has always been


part of our organisation’s plans,” said Pasha Hawaii’s chief executive officer George Pasha IV. “Our second vessel will both better serve the Hawaii/mainland market, and also provide increased frequency and superior reliability,” he added. NA
