Comments on: Preventing Oil Spills – Alternatives To Double Hull Ship Design http://gcaptain.com/ideas-in-environmentally-safe-ballast/?1081 Wed, 08 Feb 2012 23:08:17 +0000 hourly 1 http://wordpress.org/?v=3.3.1 By: Velu http://gcaptain.com/ideas-in-environmentally-safe-ballast/?1081#comment-21009 Velu Mon, 22 Sep 2008 15:01:36 +0000 http://gcaptain.com/maritime/blog/ideas-in-environmentally-safe-ballast/#comment-21009 ECDIS is something totally out of context here. I agree DH is not the only solution, but it does seem to be the best one around. Even APUS claims that less oil will be leaked into the water. The fact is that oil is still going to leak out. And how will the vaccume be created? Will we be able to maintain these systems on an ocean vessel 10 years after it rolls out of the shipyard? ECDIS is something totally out of context here.

I haven't followed the discussion but I assume this is the reason why double hull prevailed. However, neither AUPS nor DH can prevent a grounding. Another technology that was developed following Exxon Valdez pontentially can - ECDIS; it highlights and warns of charted shallow waters ahead. Unfortunately, the press seems not to take notice of it. AUPS, I gather, has a significant problem: inside a tanker’s hull free floating surfaces potentially inhibit a ship’s stability.

The truth is that after the Exxon Valdez ran aground their were a few alternatives to double hull design proposed by various parties. DH won out and now, nearly 20 years later, every layer of the industry has invested too much money for a change of this type to be done easily. That doesn't mean we can't gently remind them their are other, potentially better, ideas out there.
