    • A mudmat (24) in which the bearing plates (28) of the mudmat are fabricated of a non-corrosive, man-made structural material such as plastic. The plates, formed of such a material, are lightweight, easily fabricated and generally less expensive than the prior art plates and their associated support structure. In one preferred embodiment, the plates are formed of extruded polyvinyl chloride (PVC) or a fiber reinforced composite such as thermoset resin reinforced with glass fibers (GRP). The individual plates are supported by standard frame members (26). The PVC or GRP plates are of such a size, shape and weight that they can easily be transported to, assembled and attached to the offshore jacket at the jacket fabrication site. Being formed of such materials, the plates are corrosion-resistant, eliminating the need for cathodic protection. In addition, the PVC or GRP plates are much lighter in weight than the wood or metal plates of the prior art, such that they have less impact on the buoyancy and weight of the jackets to which they are attached. In one preferred embodiment, the plates may be corrugated to enhance resistance to horizontal and vertical displacement forces placed on the offshore jacket.
    • 泥浆垫(24),其中泥浆垫的支承板(28)由非腐蚀性的人造结构材料(例如塑料)制成。 由这种材料形成的板是轻质的,易于制造的,并且通常比现有技术的板及其相关的支撑结构便宜。 在一个优选实施例中,板由挤压聚氯乙烯(PVC)或纤维增强复合材料形成,例如用玻璃纤维(GRP)增强的热固性树脂。 单个板由标准框架构件(26)支撑。 PVC或GRP板具有这样的尺寸,形状和重量,使得它们可以容易地运输到夹套制造现场的组装和附接到离岸护套。 由这种材料形成,板是耐腐蚀的,不需要阴极保护。 此外,PVC或GRP板的重量比现有技术的木材或金属板轻得多,使得它们对附着的夹克的浮力和重量具有较小的影响。 在一个优选实施例中,板可以是波纹状的,以增强对放置在海上护套上的水平和垂直位移力的抵抗力。
