Anchoring system Spek

Overview
Spek Anchor is a conventional stockless marine anchor developed from the Hall Anchor and widely used as a bow anchor on commercial ships. Optimized fluke geometry and a lower center of gravity allow the flukes to penetrate seabeds quickly and to fit completely inside anchor pockets after recovery. Standard weights cover 100 kg to 26,000 kg and the anchor is manufactured from marine-grade cast steel. Certification options include ABS, BV, CCS, DNV, LR, NK, KR, RINA, IRS, and RS.

Introduction
Spek Anchor is a stockless bow anchor designed for merchant ships, tankers, bulk carriers, container vessels, cruise ships, and offshore support vessels. Compared with the traditional Hall Anchor, the Spek Anchor features an improved fluke profile and a lower center of gravity to allow quicker rotation into the correct working position after reaching the seabed and to allow neat stowage in modern anchor pockets. The anchor is produced by casting, heat treatment, machining, dimensional inspection, and proof testing. Production range: 100 kg to 26,000 kg, with customization available according to vessel requirements. Compatible with stud link anchor chains, end shackles, Kenter shackles, and swivel groups to form a complete anchoring system.
