A foamable composition for injecting in a region of a ship, for example to prevent and/or reduce water ingress and/or progressive flooding in the ship so as to improve damage stability of the ship, isfoamable to form a foam and is dissolvable in a removal composition. The provision of a foam, which can be dissolved by application of a removal composition, e.g., a solvent, may improve ease of removal of the foam, and therefore may reduce the cost and/or speed of reinstatement of the ship. The present invention also relates to a method of improving damage stability of a ship, the method comprising identifying one or more regions of the ship where injection of a material may lead to increase in ship stability, the material being impermeable to water and/or being capable of preventing migration of water. 种用于在船舶区域中注入的可发泡组合物，例如用于防止和/或减少船舶中的水进入和/或渐进式溢流，以提高船舶的损坏稳定性，其中可发泡组合物可发泡以形成泡沫并且可溶于去除组合物中。提供可通过施加去除组合物(例如溶剂)溶解的泡沫，可改善泡沫的去除容易性，因此可降低船舶恢复的成本和/或速度。本发明还涉及种用于改善船舶损坏稳定性的方法，该方法包括识别船舶的个或多个区域，在其中材料的注入可导致船舶稳定性增加，该材料不透水和/或能够防止水
