Investment in Design by David Tinsley, technical editor Jotun: Greening the trade in crude Bringing her first cargo to Europe fol- lowing completion by Samsung Heavy Industries, the 306,000-dwt British Pio- neer has given new expression to envi- ronmental-consciousness in the crude oil transportation sector. While the secu- rity of her 2.1-million barrel cargo con- tainment has been enhanced by the com- pulsory double hulling, the non-manda- tory continuation of the double shell aft better safeguards the bunker spaces, reducing the risk of fuel oil spillage in the event of the aftship being breached. In addition, her potential impact on marine life has been lessened through the adoption of a newly unveiled, tin- free antifouling. Although it currently comes at a very substantial price-per-liter premium, Jotun's SeaQuantum product is claimed to stand shoulder-to-shoulder perfor- mance-wise with the tin-bearing self- polishing paints, which have enabled shipowners to operate at drydocking intervals of up to 60 months. While Jotun developed the formulation for the coating, Japanese chemicals group Nip- pon Oil and Fats (NOF) came up with a silyl polymer to replace the environmen- tally hazardous tin compounds used in the ubiquitous self-polishing antifouling coatings. Multiple full-ship pilot appli- Product comparisons after drying msmsmmM Company A product Company B product Company C product cations over the past seven years provide Jotun with the basis for its claims for the long-run potency and also enhanced fuel-saving effect of the system. British Pioneer, first of a quartet for BP Amoco Shipping, is one of a host of newbuilds to be treated with the copper- based underwater coating. The anticipat- ed ban on the application of all antifoul- ings containing TBT (Tributyltin) by January 1, 2003 will focus more minds on the 'greener' alternatives.

It also allies with the trend among shipyards towards greater reliance on outsourcing. But aside from the practical advan- tages of a turnkey approach in fulfilling a newbuild program within the requisite time, budgetary and quality constraints, 'one-stop shopping' can also mean less long-term risk for the shipowner. Engine supplier Wartsila NSD and propulsor specialist John Crane-Lips are about to formalize a new pact for the delivery of complete marine power and propulsion packages. At the signing of the letter of intent in February, the Finnish group's president, Ole Johans- son, underlined the fact that this would mean "no accountability gaps" from the customer's perspective.
