THE LAST FIVE YEARS' EXPERIENCE IN STEEL PLATFORM REPAIRS

The purpose of this paper is to describe recent repair and strengthening projects on steel offshore platforms with particular reference to the cause of damage and the selected repair method. The data are used to update a detailed survey carried out in 1981. This update is based on the repair of thirty-nine structures worldwide during the period since 1981. The knowledge provided in this paper has worldwide application in the assessment of the likelihood of damage to offshore installations, the extent of damage from different causes and the most cost effective and frequently selected repair methods. The review shows that, wherever practical there is a general preference for welded repairs provided the extent of repair is limited to replacement of the original structure. However when strengthening, as opposed to repair, is required and whenever time and physical constraints (e.g. reduced diving windows, deep water, splash zone areas) apply, the use of mechanical and grouted clamping and bracing schemes is preferred. Observations are made on the typical timescale and resource requirements for different repair schemes through three case histories.
