LONDON (CNI)--The Coulombi Egg tanker design, an alternative to the double hull, has been approved in principle by the International Maritime Organization's marine environment protection committee (MEPC), it was confirmed Monday.
The Coulombi Egg design is based on a series of centre and wing tanks, divided by horizontal bulkheads. Upper wing tanks form ballast tanks which act as emergency receiver tanks for cargo should lower tanks be fractured.
Although the MEPC has ruled that the Coulombi Egg is an acceptable alternative to the double hull design, its view is not shared by the US. It has said ships built to the Coulombi Egg design will not be allowed in US ports.
