VIEW CASE STUDY

Our Modcat 1200 SD Aquacultural platform is a standard build concluded for the following application profile and is based on an actual project build. 

It is not regarded as exhaustive, and is provided as a means of providing prospective clients with a practical case study to work from.

ORIGINAL END USER REQUIREMENTS

A prestigious aquaculture client contacted us requiring a work platform required to support their existing Trout Farming operation on the Katse dam located in the mountainous kingdom of Lesotho.

Due to the high altitude, roads infrastructure and available facilities at the launch site, it was impossible for them to transport a similar conventional vessel to site.

The vessel had to be able to carry an 8-ton deck payload of fish food to the feeding station. The vessel would also be used for the retrieval and relocation of the fish cages, positioning of the mooring blocks, net change-outs and transportation of harvested fish back to the shore facility for processing.

The wheel house had to be lockable cabin fitted with clear glass windows for good all round visibility. 

Towing bollards to be fitted at the bow and the stern.

Adequate fendering to be provided along the gunnels.

In addition, a 1.5 m folding bow ramp was required for loading and unloading cargo with the use Pallet Jacks.

The client further requested that the propulsion be twin Honda 60-hp four stroke outboard motors, which would be propped to suit the platforms optimal fuel endurance and speed requirements.

SOLUTION PROVIDED: MV AQUAFARMER

We were able to use an existing design which was within the budget range proposed and provided the following solution to our client.

 

  • Modcat Platform Selected: MODCAT 1200 Single Deck - Standard Aquaculture Workboat Design.
  • The design selected was built directly off existing engineering drawings and was constructed within 2 months. 
  • Propulsion Selected: 2 x 60 HP Honda 4 Stroke Motors fitted with dual hydraulic steering.
  • The propulsion units were delivered to us by the client and fitted at our works to reduce time and labour costs at the launch site. 
  • Auxiliary Workboats Selected: The client also uses a small fleet of KFX 550 and AG 350 for personnel transport to the feeding platform and the out-lying fish cadges.

DECK LAYOUT PROVIDED

  • Open uncluttered working deck with removable safety and railings.
  • Lockable, bolt on wheelhouse housing the command station and the hydraulic deck equipment controls.
  • A 1.5-meter retractable bow ramp was supplied.  

DECK EQUIPMENT

  • 6 m Palfinger Hydraulic Crane.
  • 2.5 Ton hydraulic Capstan winch.
  • An 18 kW air cooled diesel driven hydraulic power pack was installed to provide hydraulic services to the crane and capstan. 

Seating CAPACITY

  • The vessel was certified to accommodate up to 10 people . 

SAFETY

  • The vessel was equipped to comply with SAMSA - Category R Safety Rules  

LOGISTICS SOLUTION

  • The vessel and all of the equipment was transported on a 12- and 8 metre trucks, and assembled by the Legacy Marine crew on site within 3 days.
  • The trip from our yard to site took 36 hours.

AVAILABLE SITE FACILITIES AND EQUIPMENT

  • Offloading and assembly was assisted by the use of a 3-ton fork lift and a Bobcat.
  • Assembly had to be done on a steep and uneven dam slip way.

SITE ASSEMBLY

  • Utilizing the eventual crew members as manual labour, overseen by out technical representatives, assembly took 3 days.

COMMISSIONING

  • We arranged commissioning and crew training on the numerous sea-trial voyages from the launch site to the Fish Cages over 10 km upstream.
  • Instrument calibration, Range and Performance was further tested during these runs.

PERFORMANCE, FUEL AND RANGE

  • The motors were the client’s choice for operating at 1,800m Above Sea Level.
  • They propelled the vessel with an 8-ton cargo payload at 8 knots, cruising at 3000 RPM and  consuming a total Fuel Burn of 10 litres per hour.

COST BENEFITS

  • Our shipping envelope being a normal roadway load did not require an abnormal vehicle escort and the other costs associated with abnormal load shipping, thereby substantially reducing total transport time and costs.
  • On-Site Contractor and service costs were minimal with the team using a forklift, tractor and local crew at the launch site
  • Only 3 days required on site which reduced accommodation and labour costs considering the location.
  • Vessel fuel efficiency and payload factors exceeded all expectations.
