The Admiral Day
Admiral Day (Grab Hopper Dredger)
Built in 1971 The Admiral Day has been modernised and fully renovated by Wyre Marine to be the vessel she is today. She has been fitted with a long reach excavator and equipped with a range of buckets to enable dredging in a wide variety of materials. The hopper well is fitted with a grid to avoid debris being deposited at sea and discharges via hydraulically operated bottom doors. She is our largest vessel and capable of holding large loads therefore allowing us to complete projects in a timely manner and thus reducing impact to marine traffic/harbour daily operations.

The DoonHamer |

The vessel 'Doonhamer' was built in the United Kingdom in 1991. In 2014 Wyre Marine Services fully renovated and modernised the vessel so it would be built for its purpose as a self-sufficient water injection dredger.
Water injection is a hydrodynamic dredging technique that should be taken into consideration as a cost-effective, environmentally sound solution to some specific dredging operations. Injecting high velocity water close to the seabed creates a density current that then, either by the force of gravity or natural currents flows downwards to deeper water. This all occurs with a minimum of disturbance to the equilibrium of the ecosystem. Therefore, instead of mechanical transportation, nature takes care of the sediment transport.
The Doonhamer can also reach restricted areas more than other dredging techniques as she can inject water under pontoons, moored vessels etc. allowing disturbance to marinas kept to a minimum.

Wyre Sands |
Originally built in 1997 Wyre Marine purchased Bardera Segundo in 2018, and renamed her Wyre Sands after completing a full refurbishment. She is a steel built Grab Hopper Dredger with a fitted 35 tonne long reach excavator which is capable of a digging depth of 10 meters. Smaller in size than the Admiral Day she is capable of dredging the most restricted areas.
Year of Build 1997- Full Refurbishment Completed 2018 Port of Registry: Fleetwood, UK Gross and Net Tonnage: 90.92 Length: 24.60 meters Breadth: 8.0 meters Draft: 2.4 meters Depth 3.0 meters Hopper Capacity: 120m3 |
Wyre River

Wyre River (originally named Solent Hopper) is of newest vessel to the fleet. Built in Southampton 1954, She has just undergone a full refit and been modernised to a high professional standard. Wyre River has a 180m³ capacity, self-propelled, bottom door hopper barge. She is a highly maneuverable vessel, capable of accessing restricted sites. The Wyre River is ideal for capital and maintenance dredging, beach replenishment and coast/pipeline protection projects. The vessel works alongside the company’s modular pontoon spud leg pontoon and other hopper dredgers, or may be used solely.
