Fixed steel lighthouse towers for breakwater heads, harbour entrances and coastal hazard points. Steel structure manufactured at our İzmir facility; combines day mark and night lantern function in a single tower. We engineer the tower, lantern, radar reflector and power system together — single-supplier delivery from site survey to commissioning.
Land-based direction tower at harbour entrances, channel edges and shallow water hazard points. Type 1 or Type 2 cylindrical/conical tower with internal ladder and top lantern platform is the standard harbour marking solution.
Fixed land tower marking breakwater heads, rocky coastlines, islets or shallow water hazards at all times. IALA colour band application provides daytime visibility; flashing lantern at tower top completes the night marking.
Turnkey service covering tower selection, manufacturing, transport and site installation for new harbour, fish farm perimeter and coastal safety projects. ASAKUA teams execute site installation on international projects.
Type 1 cylindrical body with internal ladder, Ø500 mm and above — the standard configuration for harbour and breakwater projects. Type 2 conical body with internal ladder, same diameter range with a more dynamic silhouette. Type 3 cylindrical body with external ladder, optimised for compact projects below Ø500 mm.
All types serve as a day mark through IALA-compliant colour band application; the ASAKUA flashing lantern at the tower top completes night visibility. Radar reflectors, solar power systems and remote monitoring can be integrated on request. As an IALA member, ASAKUA tracks marine aids to navigation standards directly.
Every tower is designed against site data — height, nominal range, wind load and grid/solar choice are evaluated per project. Engineering, fabrication, transport and on-site installation are delivered turnkey by ASAKUA teams. We have active structures in harbour, breakwater and coastal safety projects across 39 countries.
