High strength concrete provides joint protection
- Offshore Joint Services, Houston, TX (US)
This paper reports on a joint fill material applied on the 24-in. pipe used by Iroquois Gas Transmission Project for its 26-mile Long Island Sound crossing which provides effective joint protection. The 3.35-in. joint fill, made of high instant strength concrete, met stringent requirements for both strength and weight coating, and is environmentally clean to protect the sensitive marine ecosystem. The offshore section, from Bridgeport, Conn., to Long Island, was laid by McDermott, Inc. The high instant strength concrete supplied joint strength and protection during the laying operation, and on the barge itself, where pipe joints are most vulnerable to damage. With joint fill density the same as the concrete already on the pipe, the submerged weight was uniform along the entire length of the marine line, for an essentially seamless coating.
